Scarlett Johansson finds technology 'crazy'

Johansson has given her voice to the operating system named Samantha in the Oscar-nominated film "Her".

"All of it drives me crazy. I don't understand this need to 'share'. We almost exploit ourselves in order to feel seen," the 29-year-old said in a statement.

"I don't have a Facebook or a twitter account, and I don't know how I feel about this idea of, 'Now, I'm eating dinner, and I want everyone to know that I'm having dinner at this time,' or 'I just mailed a letter and dropped off my kids'. I'd rather that people had less access to my personal life," she added.

"Her" follows the life of a heartbroken man who becomes intrigued with a new, advanced operating system, which promises to be an intuitive entity in its own right, individual to each user.
